Managing the Firmware Image
6-2 Firmware Image and File Management
Downloading from a TFTP or SFTP Server
This procedure assumes that the switch or stack of switches has been assigned an IP address and
that it is connected to the network. It also assumes that the network has a TFTP or SFTP server to
which you have access. If these assumptions are not true, please refer to Chapter 1, Setting Up a
Switch for the First Time for more information.
To perform a TFTP or SFTP download:
1. Download to your computer the latest firmware for the switch from the Enterasys web site
Unzip/uncompress the firmware, and copy the firmware to the upload/download directory
configured for your TFTP server. The firmware is available at this Enterasys location:
https://extranet.enterasys.com/downloads
2. Review the Release Notes for the downloaded firmware to check for any upgrade notices or
limitations that may apply to your switch.
3. Using Telnet or SSH, establish a CLI session on the switch and log in.
4. From the CLI session, use the copy command to download the new image file from the TFTP
or SFTP server to the switch. For example:
copy tftp://<TFTP-server-IPaddr>/<path-to-firmware-file> system:image
If you receive the error message “Error: No space left on the device. Please remove backup
file.”, refer to “Deleting a Backup Image File” on page 1-5 before proceeding.
5. After the copy is complete, use the dir command to confirm that the new image file has been
copied. The following example shows that the firmware image “a4-series_06.61.03.0007” was
copied to the switch but that firmware image “a4-series_06.61.00.0026” is still the active and
boot image.
